Spell Design Help: Activating wands at a distance

[Volaran]

Hello there

My character in a friend's campaign has some downtime coming up, and the extra funds for spell research. My last aquired feat was "Craft Wand" and I'd like to get a little extra mileage out of it.

So, I was thinking of designing a spell to let my character activate a wand he'd created from a distance. Perhaps useful for setting off an ambush, or for causing mayhem if the party is captured. I'm not sure what level would be appropriate for such a spell, or what other considerations might apply.

So, the parameters I'd surely like to have would be:
Ranged Activation, though I haven't set my mind to precisely what range.
Verbal component only
Casting time of one action
Useful only with wands, and specifically only wands crafted by the spellcaster

Any thoughts on that? Would designing a higher level spell later that activated multiple wands be gamebreaking?

Awaken from Afar
Evocation
Level: Sor/Wiz 5, Clr 6, Drd 6
Components: V
Casting Time: 1 action
Range: Medium (100 ft. + 10 ft./level)
Target: One spell trigger activation item
Duration: Instantaneous
Saving Throw: None
Spell Resistance: No

An awaken from afar spell allows you to use a spell trigger item without actually touching the item. The item to be activated must be within the range of the awaken from afar spell, and it functions as though you yourself were triggering it from its current position. All other conditions, such as the requirement that you have the spell on your spell list or if the item’s enchantment restricts its use to a particular race or individual, still apply. Both you and the item to be activated have to be on the same plane. The item cannot be in the possession of another creature at the time of activation, and it must be an item that you have previously triggered normally (in other words, without the aid of an awaken from afar spell.

Thank you kindly. Useful on its own, and to reverse engineer for lesser versions.
